[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail;

[0026] This application discloses an intelligent maintenance device for signal transmission lines in broadcast television engineering. (Refer to...) Figures 1-6 A smart maintenance device for signal transmission lines in broadcast television engineering includes a maintenance device body 1. A line access module 2 is installed at the rear end of the maintenance device body 1. The line access module 2 is electrically connected to a signal monitoring module 3. The signal monitoring module 3 is signal-connected to an intelligent analysis module 4. The intelligent analysis module 4 is signal-connected to an alarm and display module 5. By installing the signal monitoring module 3 and the intelligent analysis module 4, when the line access module 2 is connected to the main line or branch line via a high-frequency coaxial connector or fiber optic connector, and can be connected through a splitter, looper, or other structure, the signal monitoring module 3 monitors the line signal strength, voltage, current, reflection loss, bit error rate, etc., to determine the integrity of the line connection, signal attenuation, and the presence of electrical faults. The intelligent analysis module 4 then analyzes the signal parameters to identify abnormalities. The intelligent analysis module 4 has a built-in microcontroller or edge computing chip, combined with set thresholds and feature algorithm models, to quickly judge the collected data. This enables the device to perform real-time monitoring of signal transmission status, automatic fault diagnosis, remote notification, and local maintenance assistance, improving the practicality of this smart maintenance device for signal transmission lines in broadcast television engineering.

[0027] Reference Figure 1 , Figure 2 and Figure 6 The alarm and display module 5 is connected to the communication module 6. By installing the alarm and display module 5, which consists of a display screen and indicator lights, the display screen shows the detection parameters in real time, and the LED red and green indicator lights can quickly determine the status. The buzzer alarms when a serious abnormality occurs, which facilitates the first response of on-site maintenance personnel. In conjunction with the communication module 6, which is formed by cellular network 4G or 5G, Wi-Fi or wired Ethernet, the detection results are remotely transmitted to the operation and maintenance center or mobile APP, realizing unattended operation and remote maintenance, and improving the maintenance convenience of the device.

[0028] Reference Figure 1 and Figure 3 The bottom of the maintenance device body 1 is fixedly connected to a base 7, and the bottom of the base 7 is fixedly connected to a symmetrically distributed support frame 8. A pair of motors 9 are installed on the inner end of one side of the support frame 8. By installing the support frame 8, the pair of support frames 8 can form a support connection structure outside the movable adjustment component at the bottom of the device, making the connection and installation between the movable adjustment component and the base 7 and the maintenance device body 1 more stable.

[0029] Reference Figures 3-5The transmission end of the motor 9 is fixedly connected to a bidirectional lead screw 10. The outer end of the bidirectional lead screw 10 is threaded with symmetrically distributed moving blocks 11. By installing the moving blocks 11, starting the motor 9 can drive the bidirectional lead screw 10 to rotate. The rotating bidirectional lead screw 10 can drive a pair of moving blocks 11 to perform threaded action. The pair of moving blocks 11 can move in opposite directions, thereby driving the lifting frame 12 to adjust its position, which improves the convenience of the cooperation between the structures of the device.

[0030] Reference Figure 3 and Figure 4 Each movable block 11 is hinged to a lifting frame 12 at its outer end. The other end of the lifting frame 12 away from the movable block 11 is hinged to a reinforcing block 13. By installing the lifting frame 12, the cross-connected lifting frame 12 can be folded, retracted, and extended under the movement adjustment of a pair of movable blocks 11. Under the action of force, it can drive the connected movable wheel 14 to adjust its position, so that the movable wheel 14 can retract and extend. This allows the device to be easily moved to the preset coverage area of ​​the broadcasting and television project for maintenance and testing at various locations during use and maintenance, thus improving the ease of use of the device.

[0031] Reference Figures 3-5 The bottom end of the reinforcing block 13 is equipped with a movable wheel 14. By installing the movable wheel 14, multiple movable wheels 14 can facilitate the movement of the device.

[0032] Reference Figures 1-5 Each reinforcing block 13 has a slider 15 fixedly connected to its outer end. The outer end of the slider 15 is slidably connected to a guide frame 16. The guide frame 16 is located at the bottom of the base 7. By installing the guide frame 16, a sliding groove is opened at the inner end of the guide frame 16. When the lifting frame 12 adjusts its position and drives the reinforcing block 13 and the moving wheel 14, the reinforcing block 13, in conjunction with the external slider 15, slides at the inner end of the guide frame 16. This prevents the lifting frame 12 and the reinforcing block 13 from shifting or falling off during position adjustment, thus improving the adjustment stability of the moving components of the device.

[0033] Reference Figure 1 and Figure 3 Each movable block 11 has a sliding block 17 fixedly connected to its top end. The inner end of the sliding block 17 is slidably connected to a guide rod 18, which is located at the inner end of the support frame 8. By installing the sliding block 17 and the guide rod 18, when the movable block 11 is adjusted in position, the sliding block 17 moves and adjusts together with it. The moving sliding block 17 slides at the outer end of the guide rod 18, so that the movable block 11 will not flip or shift when it is adjusted in position, which further improves the adjustment effect between the movable components.

[0034] Working Principle: When in use, this device first connects to the main line via line access module 2. Signal monitoring module 3 collects signal parameters in real time and transmits them to intelligent analysis module 4. Intelligent analysis module 4 judges the signal status. If abnormal levels, excessively high bit error rate, or current fluctuations are detected, it records and triggers alarm and display module 5. Alarm and display module 5 consists of a display screen and indicator lights. The display screen shows the detected parameters in real time, and the red and green LED indicators quickly determine the status. Then, communication module 6 synchronizes the fault information to the maintenance center backend or sends it to the maintenance personnel's mobile terminal, enabling convenient maintenance of the device. Before use, starting the motor 9 can drive the bidirectional lead screw 10 to rotate. The rotating bidirectional lead screw 10 can drive a pair of moving blocks 11 to perform threaded action. The pair of moving blocks 11 move in opposite directions, which can drive the lifting frame 12 to adjust its position. The lifting frame 12, which is cross-connected, can be folded, retracted, and extended under the movement adjustment of the pair of moving blocks 11. Under the action of force, it can drive the connected moving wheel 14 to adjust its position, so that the moving wheel 14 can retract and extend. This allows the device to be easily moved to the preset coverage area of ​​the broadcasting and television project for maintenance and testing at various locations during use and maintenance, thus improving the use and maintenance effect of the device.
